HI. so glad I found this forum. My sweet Dolly is 9 years old and I found out this week she is diabetic. Took her to the vet because her breath was very stinky. She has a bad mouth and needs two teeth removed. While examining her the vet said her heartbeat was not normal and her thyroid was "flabby" and did blood work. She is on glipizide 5mg, 1/2 tablet twice a day. She is also taking an antibiotic for her mouth. Her vet recommended Purina DM canned, which I thought was expensive, she also said Fancy Feast Classic is also okay. I am using the Fancy Feast. Both cats, she has a brother, get wet food twice a day and dry food, free fed. I know the dry can be high in carbs and bought a bag of grain free, I also am slowly cutting back on the amount I put in the bowl. I now measure it. Her vet did not mention anything about home testing. I hope the food choices I have made due her no further harm.
